One thing is storage density, another is data transfer rate. Frontier's LustreFS based mind-boggling 700PB Orion storage subsystem writes at a similarly impressive 5TB/s [1]; so with a generous reading, it could potentially fill up in about 39h. Historically, disk density increased more rapidly than network bandwidth, which ultimately limits the performance of distributed file systems. If it takes weeks or months to write such enormous data set, then there will be only few use cases, if it takes years there will be none.
